I found I have Group B

Im so happy I have 1 week to go but now Im worried. Going to the dr's tues I found that I have strep. only a little bit and Ill need anti biotics ant birth time. Im freaken out because I want every thing to be ok an hopefull ill not need a cecerian like my sister needed. It was because she had strep also. o man I hope it comes out to be ok in the nd and my baby wont get sick because I hear strep gets the baby sick coming true the cannal. Its so difficult because im a 1st timer at all this

I actually just had thist test and my doc said it came back neg. but my friend told me that her doc told her that she was neg. both times and come to find out when she went to the hospital she had it.... have you heard of this before?
